Abstract

Introduction and objectives: The duration of the QRS interval measured by ECG is a marker of ventricular dysfunction and indicates a poor prognosis. Major adverse cardiovascular events defined as cardiac death, reinfarction, heart failure, cerebrovascular event, sustained ventricular tachycardia or fibrillation. Low cardiac output syndrome was defined as usage of inotropic or intraaortic balloon pump support. Its value in patients undergoing coronary revascularization surgery has not been established. Methods: cross sectional description. The study involved 171 consecutive patients scheduled for elective coronary surgery at Hanoi Heart Hospital from 6/2016 – 8/2018. The maximum QRS duration measured on a preoperative 12-lead ECG was recorded. Main results: Mean age 65,05 ± 7,41 years; 78,4% male. The occurrence of hemodynamic instability (n=45, 26,3%) was associated with a longer preoperative QRS duration. The QRS duration was also longer (QRS ≥ 90 miligiây) in patients who developed acute heart failure need inotropic drugs (36,4% vs 15,7%; p < 0,05). Conclusions: The intraventricular conduction delay, or QRS duration, was associated with a higher risk of postoperative hemodynamic instability following coronary surgery. 1
